The video part works great, however the audio part is still giving trouble. If I try encoding in mp3, the following happens (on the console with -debug subproc) : ::EXEC:: mplex test.mpg test.mp3 test.mps *************************************************************** * MPEG1/SYSTEMS Multiplexer * * (C) Christoph Moar, 1994/1995 * * moar@informatik.tu-muenchen.de * * Technical University of Munich * * SIEMENS ZFE ST SN 11 / T SN 6 * * * * This program is free software.

Segmentation fault - core dumped ::STATUS:: 139 Command Failed: mplex test.mpg test.mp3 test.mps Conversion Aborted. What strikes me as odd is that 24.000 frames/sec -- I set it to 10 frames/sec in the dialog. If I do encoding with mp2, the conversion finishes ok, but playing with mtv or a ~doze player displays the video correctly, but the sound is just a short *blop. When doing just audio recording, both mp2 and mp3 are ok, this makes me think that the problem lies somewhere in mplex. I went thru the (somewhat sparse) documentation of mplex, couldn't find anything useful.... any idea ?? Thanks for all the help so far, hope I didn't hit the annoyance threshold yet -- -Th To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
